Abstract
A number of xenobiotics by mimicking natural hormones can disrupt crucial functions in wildlife and humans. These chemicals termed endocrine disruptors are able to exert adverse effects through a variety of mechanisms. Fortunately, there is a growing interest in the study of these structurally diverse chemicals mainly through research programs based on in vitro and in vivo experimentations but also by means of SAR and QSAR models. The goal of our study was to retrieve from the literature all the papers dealing with structure-activity models on endocrine disruptor xenobiotics. A critical analysis of these models was made focusing our attention on the quality of the biological data, the significance of the molecular descriptors and the validity of the statistical tools used for deriving the models. The predictive power and domain of application of these models were also discussed.

Abstract
A series of 2-(N-aryl-N-aroyl)amino-4,5-dihydrothiazole derivatives have been synthesized via cyclocondensation of N-aryl thioureas with 2-bromoethylamine hydrobromide followed by the reaction of the product thus obtained with aroyl chlorides. Title compounds were evaluated for their antithrombotic activity in vivo in mice where one of these compound 29 provided 65% protection as compared to 77% protection offered by the standard Indomethacin. Quantitative Structure-Activity Relationship (QSAR) studies were performed on these compounds using physicochemical (hydrophobic, electronic, steric) parameter as independent and antithrombic activity as dependent parameter, where antithrombotic activity correlated best (r > 0.8) with electronic parameters (F, sigma or mu) having high statistical significance > 99.9% (F(2,22)>15.0; F(2,22alpha:0.001)=11.0) suggesting that hydrophobic, steric and resonance factors are insignificant in this set of molecules for the activity.

Abstract
Shape complementarity, electrostatic and hydrophobic matching, were used to model drugs and receptors. From known experimental data on alpha1A/alpha2A-adrenergic ligands and alpha1A/alpha2A-adrenoceptors, a model for the ligand binding sites, based on the structure of bacteriorhodopsin as a template, was proposed and built. Agonists and antagonists have overlapping but different binding sites. Emphasis was given on the role of the disulphide bridge and on the role of the sodium site. The model was extended to other G-protein coupled receptors.

Abstract
Carbaryl belongs to a series of compounds that activate the CYP1A1 gene. This study demonstrates the inability of carbaryl to compete with 2,3,7,8-tetrachlorodibenzo-p-dioxin for binding to the rat aryl hydrocarbon (dioxin) receptor. Structural and physicochemical properties of this insecticide, in relation to the requirements for binding to the aryl hydrocarbon receptor, are described. The crystal structure was determined experimentally using X-ray diffraction. A conformational search using molecular mechanics was performed by means of a Monte-Carlo-type method and a stochastic dynamics simulation. Lipophilicity calculations, log P, and molecular lipophilicity potential are also presented. Common and discriminating properties of carbaryl and aryl hydrocarbon receptor ligands are discussed.

Abstract
Activation of the CYP1A1 gene has been described to be mediated by the cytosolic Ah receptor (AhR) and a possible cooperative role of the 4S benzo(a)pyrene-binding protein (4S protein). Carbaryl (CAR) has been shown to induce human CYP1A1 gene expression without binding to the human AhR. In this study, Sprague-Dawley rats received a single i.p. dose of 20, 80, 150 micromol/kg CAR or NAPn (naphthalene, the aromatic part of CAR) and were sacrificed after 24 h. CAR increased ethoxyresorufin-O-deethylase and methoxyresorufin-O-demethylase activities, the level of CYP1A1, 1A2 proteins, and CYP1A1 mRNA at the highest dose, whereas NAPn showed no effects. Moreover, CAR, naphthol (its major metabolite) and NAPn were not ligands in vitro of the TCDD binding site of AhR or the benzo(a)-pyrene binding site of 4S protein in rat, neither was CAR a ligand of these two binding sites in mice, dog, monkey or human. Molecular properties of CAR were evaluated and showed that this molecule is far from the structural characteristics of CYP 1A1 specific inducers although a planar conformation can be achieved with an energy < 5 kJ x mol(-1). The data demonstrated that CAR could also modulate the AhR-mediated responses, even though it did not meet the structural requirements to be ligand of AhR.

A series of fused pyrazole derivatives of cyclolignans have been prepared through simple chemical routes and evaluated for their cytotoxic activities in culture cells of P-388 murine leukemia, A-549 lung carcinoma and HT-29 colon carcinoma. Despite the lack of the lactone moiety in their structures, they show IC50 values at microM levels.

Abstract
The diastereoselective synthesis is reported of a dipeptide template which is closely related to H-Gly-Trp-OH. Intramolecular bond formation between alpha-C of Gly and ring position 2 of the Trp unit has been achieved by a Pictet-Spengler-type electrophilic aromatic substitution. The absolute configuration of the N-Moc protected dipeptide template 9.2H2O was determined by single-crystal X-ray crystallography and found to be (2S,5S). The cis orientation of the amino and carboxy termini prompted us to investigate the potential of 9 as a beta-turn mimic. MD calculations on the model pseudopeptide Ac-Ala-Gly-Trp-Ala-NHMe 11 suggest that an unusually tight turn should be favoured rather than a beta-turn. The proper protective situation as a pre-requisite for the incorporation of the template into a peptide has been established, and comments about its chemical properties are given.

Abstract
If the geometrical pharmacophore of 5-HT3 receptor antagonists has been proposed by different authors, the electronic and lipophilic features of the ligands had to be precised. A 3-D QSAR study has enlightened the importance of three parameters derived from molecular electrostatic and molecular lipophilicity potentials. A multiple linear regression equation has been established. Its predictive character (non specific binding of 3[H]-ICS 205-930) has been tested with success for three different new ligands.

Abstract
A series of 5-(1-aryl-4-piperazino)methyl-2-amino-2-oxazolines has been prepared and screened for antidepressant activity. Their lipophilic behaviour has been discussed in relation to the nature and the position of substituents on the aromatic ring. The influence of steric effects on the pharmacological activity has been investigated using experimental methods (X-ray diffraction, NMR) and theoretical calculations (semi-empirical quantum mechanics). The ortho-substitution on the phenyl ring or the C-alpha substitution on the piperazine ring by a methyl group results in the same effects i.e. an increase of the angle between the two rings up to 64 degrees (X-ray and calculation) and a loss of the antidepressant activity. Using NMR, only the influence of the ortho-substitution has been observed.

Abstract
A series of anti-thrombotic aryl thienyl-ketones and -thioketones was assayed in vitro for their inhibitory effect on malondialdehyde (MDA) production induced by arachidonic acid in human platelets. For several compounds MDA formation was strongly inhibited indicating that the anti-platelet target was situated on the cyclooxygenase pathway. A comparison between the inhibition constant Ki and the IC50 values revealed competitive inhibition kinetics. The molecular structure of one active compound was analysed by X-ray diffraction and theoretical calculations to provide information on its electronic and lipophilic properties.
